In recent years, the scientific community has emphasized the importance of the core both in the sports context and in rehabilitation. The core is an area of the body, responsible for generating force from the center and dissipating it to the extremities. In this perspective, specific exercises have been used for this area in functional training, in order to promote improvements in functional and core performance. However, it is not clear in what magnitude the core actually participates in performing functional actions in young adults and yet whether the inclusion of core-specific physical exercises in functional training causes more pronounced functional adaptations than when this inclusion does not occur. Thus, the objectives of this dissertation were: I) To analyze the association between the endurance of the core and measures of functional performance in young individuals. II). To analyze the effects of 12 weeks of specific core training and functional training, with and without the inclusion of core-specific exercises, on core performance and performance in functional tests. This dissertation was composed of three studies: A study of protocol / trial (Study I), transversal (Study II) and experimental (Study III). Participating in the study sample were young and healthy individuals, classified as insufficiently active by the International Questionnaire of Physical Activity. In the study II a multiple linear regression was performed with the purpose of explaining in what magnitude the endurance of the core contributes to the performance of functional tests. The findings of this study showed that there is a participation of core endurance ranging from 1.4 to 46.9% depending on the functional test performed. In addition, most of these interactions were statistically significant. In study III, the participants were allocated to three intervention groups: Functional Training with core, which performed global exercises in addition to specific exercises for the core; Functional training, which performed only functional global exercises; and Core training, which performed only exercises that caused greater activation in the core muscles. After 12 weeks of training, all groups improved significantly in both functional and core performance, but there were no significant differences between them. Thus, it is concluded that the endurance of the core is important for the functionality of young adults and that when core-specific exercises are included in the functional training, the gains related to functional and core performance are enhanced.
